" zaatl'whomz'tlhayconcemf Be it known that I, WALTER R. Sermon, a'citizen of the United States, and a resident of Monmouth,'in the countyof War-- ren and State of Illinois, have invented a new and usefulPetcock Opener -and Closer f for.Automobile Crank-Casesfof which thefollowing is a specification My invention relates to a device wherebythe pet-cocks of automobile'crank-cases may be manually opened withouteffort, and

without'either reaching or getting under the car, and which willautomatically close them.

when the manual operation ceases; and the invention consists,substantially, in the improvementsherein described. f

In the accompanying drawings, which illustrate a'practical and preferredembodi= ment ofmy inventionzFigure 1 is a side elevation showing thefront portion of an automobile with my improvement'attached thereto andillustrating. the conveninlrand accessible position in which it isplaced. Fig. 2,

'a rear elevation, showin the attachment of v 26 thedevice to thepe't-co'c s of the crank-case.

Struck inward from the lower edge of thetube are lips 16 on Which'is as supported a washer 17 which seatsalso'onthe shoulder 6.

Assume, then, theparts ofi th e de- 80. vice to-be in the relative positions: thereshow-n, and that it is desirable to open the pet cocks, in order toascertain how much oil is in the crank-case, or for any other purpose,the operator will, by means of the handle 5 draw on the rod 4, therebyshifting all the elements to the position shown in Fig. 3 or, of courseto any intermediate one desired. This movemdi'i compresses the spring14, for the head of th asing 15 abuts against the fender 18 and theshgulder 6 will I draw themovable washer 17 up ard, ;an d the sprin will be compressed againstfthe head of t e'gasing.

It has not been thought necessary to encamber this Specification and theaceomcomprising a sprmg-case a spring coiled "dongitudmally thereof andtherein, one of panying drawings with descriptions andillustrations ofmodifications or of elements which are neither essential to nor formanypart oftheinvention herein claimed.- In fact, it is apparent withoutsuch that numerous changes may be made in the details of constructionand by modifications involving only mechanical skill, without departingfrom the spirit and scope of the invention.

Therefore, without limiting myself to particularities I claim as new anddesire to secure by Letters Patent the following, to-wit:

1. A device of the character described comprising a'push-rod, a sp ngfor moving it in one direction, a bifurcated link straddling one end ofsaid rod md pivoted thereto, and a pair of bell-crank levers each ofwhich has a bifurcated end pivoted to said link.

2. A device of the character described comprising a push-rod, a springfor moving it in one direction. a bifurcated link straddling one end ofsaid rod and pivoted there to, and a pair of levers each of which has abifurcated end pivoted to said link.

3. In an automobile, the combination with the pet-cocks of thecrank-:case and with one of the fenders, of yieldingr-means attached tosaid fender and adapted to hold both petcocks normally closed, and meansfor simultaneo'usly opening both pet-cocks. v

4. A device of the character described its ends restrained by a portion.of the spring-case, a washer reciprocable in the spring-case, itsmovement-in one direction limited by aportion of said case, a push-rodhaving a shoulder adapted to move said washer in said case to therebycompress the spring, a bifurcated link straddling one end of said rodand pivoted thereto, and a pair of levers each of which has a bifurcatedend pivoted to said link.

5. A levice of the character described comprising a spring-case, apush-rod movable therein, a spring in said case and adapted to move saidrod in one direction, a bifurcated link pivoted to one end of said rod,and a pair of levers each of which has a bifurcated endpivoted to saidlink.

6. A device of the character described comprising a spring-case, apush-rod movable there1n,'a spring arranged in said case and adapted tomove said rod in one direction, a bifui'cated link straddling one end ofsaid rod and pivoted thereto, and a pair of bell-crank levers each ofwhich has a bifurcated end pivoted to said link.

In testimony that Iclaim the foregoing as my own, I hereunto ailix mysignature.
